SPECIFICATION forming part f Letters Patelt No. `315,362, dated April 7, 1885.

Y Application filed November 19, 1884. (No model.) A

To all whom t may concern:

Be it known that I, BENJAMIN WEAvEE, of

Pittsburg, in the county of Allegheny and- State of Pennsylvania, have invented certain new and useful Improvements in Guide-Boxes; and I do hereby declare that the following is a full, clear, and exact description of the invent'ion, which will enable others skilled in the art to which it appertains to make and use the same, .reference being had to the accompanying drawings, which form a part of this specification.

This invention has relation to guides 7 for rolling-mills, and has for its object to provide a guide which Vwill be of such construction that any inequalities of the grooves in the guide may be speedily and perfectly adjusted; or, in other words, when it is desirable to adjust the guides, it can be done in a perfectly exact manner, with but little loss of time and labor.

In the guides for rolling-mills as now generally constructed, when one side-of the working groove in the guide becomes worn or uneven, and it is desirable or necessary to adjust the same, the usual method is to remove the side that is worn and raise it to the level of the other side by placing under it thin plates or sheets of iron. This method consumes considerable time and labor, and then is far from being satisfactory, as it is almost impossible to perfectly adjust the guides in this way.

My invention consists of the novel construction, combination, and arrangement of parts, as hereinafter described and claimed.

Referring to the accompanying drawings, Figure 1 is a vertical section of a pair of rolls and the guide-box; Fig. 2, a front view of a pair of rolls with the guide-box in position; Fig. 3, an enlarged section of the guide-box on line aa x of Fig. 2, and Fig. 4 a side view of the wedge which I employ to adjust the height of the guides.

A A designate the rolls, and B B the housings in which said rolls are supported. C desi gnates the guide-box, which consists of a rectangular casing attached to the housings B B at each end and immediately in front of the rolls A A. The guide-box C is provided at its center, or opposite to the grooves in the rolls A A, with two guides, D D. Said guides consist of a rectangular body of metal adapted .to t loosely in thebox C and project slightly therethrough, the inner ends being brought to an edge, so as to approach as closely as possible to the two rolls A A, as shown in Fig. l of e the drawings.

E E E designate filling-pieces which are,` placed in the box C between the guides D D and the end of the box, and F Fare set-screws passing through the ends of the box, and serve ing to retain in position and adjust longitudi-` 4nally the guides.

G G are similar screws passing through the top of the guide-box above the guides D D', and bearing against the latter.

Upon the bottom of each of the guides D D is formed a groove, d d', running the entire length of said guides, said grooves being deeper at the front and gradually tapering to the end of the guide, which is adapted to receive .the tapered key or wedge H, which is shown separately in Fig. 4; and in order that the work` The mode of operating my invention is as follows: The guides and llinglpieces being prop'ierly centered in the guide-box by means i of set-screws dF F, the wedge H is inserted in the groove d of one or the other of the guides `D D', as the same may require by reason of e the inequality of the grooves in the guides,

and the screws G Gr turned down until the guides are firmly held. The guides are prevented from being pulled through the guide! box and against the rolls by anges I I, which are formed upon the upper edges of their outer ends. The guide beneath which the key or Wedge has been placed may be nicely adjusted by turning the screws G and h', and

roo

when, by reason of any inequalities in thev Working groove, it becomes desirable to adj ust the guide, it may be done Without removing it from the boX.

Having described my invention, I claiml. In a guiding device for rolls, the combination7 with the guide-box C, ofgrooved guides adjusted vertically in said box by means of a Wedge inserted in a longitudinal groove in the bottom of the guide and a screw passing through the top of the guide-box and bearing on the guide, substantially as described.

2. In a guide for rolls7 the combination of a guide-box, having set-screws G G in its top,
